where \(M_{exp}\)  is the theoretical SO moment, one has \(M\)  = 0.8 \(\mu _B\) /f.u., now closer but still larger than the experiment. Such discrepancy to the value expected for a linear Co–Fe AFM coupling gives evidence toward the spin canting scenario, since the small net magnetization values depicted in Table REF  are of the same order of magnitude as those reported for spin canted Ir-based DPs [1]}, [2]}. However, the possibility of NCM with two distinct AFM superlattices for the Fe/Co and Ir sites can not be completely excluded since other ingredients besides ASD may contribute to the further decrease of the magnetization, as for instance antiphase boundaries, oxygen vacancies and defects that could lead to local changes in the TM ions valences, as the afore discussed possible presence of some small amount of Co\(^{3+}\) . Again, further investigation is necessary to determine whether the FIM-like behavior of LCCFIO results from uncompensated Co–Fe AFM coupling, from spin canting or even from a simple AFM coupling between Co/Fe and Ir FM sublattices.
